Evaluation Kit

Detailed Description of Software

The MAX77960/MAX77961 GUI software provides an easy-

to-use interface to control the function blocks of the IC.

Software Installation

Double-click the

MAX77960_MAX77961GUISetup-

X.X.X.exe icon to begin the installation process. Follow

the prompts to complete the installation. The evalua-

tion software can be uninstalled in the

Add/Remove

Programs tool in the Control Panel. After the installation

is complete, open the

Maxim Integrated/MAX77960_

MAX77961 folder and run MAX77960_MAX77961.exe

or select it from the program menu. Figure 3 shows a

splash screen containing information about the evaluation

kit that appears while the program is loading.

Establish Communication

Power up the MAX77960/MAX77961 by connecting a

2- or 3-cell Li-ion battery or simulated battery at BATTP/

BATTN. Open the GUI software and select

Device >

Connect. A window should pop up showing that a slave

address 0xD2 has been found. If not, check the USB

connection and power. Choose

Read and Close and the

status bar displays “Connected” to signify active commu-

nication. An example of a successful connection is shown

in Figure 4.

INLIM

1-2

1-2: Connects INLIM to PVL. Default input current limit is same as

decode of reset value of CHGIN_ILIM[6:0].

2-3: Connects INLIM to R51. Default input current limit is programmed by

R51.

J11

ITO

1-2

1-2: Connects ITO to PVL. Default top-off charge current is same as

decode of reset value of TO_ITH[2:0].

2-3: Connects ITO to R52. Default top-off charge current is programmed by

R52.

J12

ISET

1-2

1-2: Connects ISET to PVL. Default fast-charge current is same as decode

of reset value CHGCC[5:0].

2-3: Connects ISET to R53. Default fast-charge current is programmed by

R53.

J13

THM

2-3

1-2: Connects THM to potentiometer R39. Adjust resistance of R39 to

emulate resistance change of a 10kΩ thermistor at different temperature.

2-3: Connects THM to a fixed 10kΩ resistor. This emulates resistance of a

10kΩ thermistor at 25°C.
